In this paper, we present a sensing scheme for STT-MRAM with 1T1MTJ common SL structure array: covalent-bonded cross-coupled current-mode sense amplifier (CBSA). The CBSA can fit in conventional DRAM array architecture and use two normal cells adjacent BLs, one storing data "1" the other "0", generating reference currents CBSA. There are 64 CBSAs row of 8k cells, where references BLs shared by 128 BLs. cell is directly accessed instead page opening as DRAM. By introducing schemes,...

Recent findings have demonstrated that the desalination and purification of contaminated water, separation ions gases, besides solutions to other related issues, may all be achieved with use membranes based on artificial nanoporous materials.

To monitor large areas or simultaneously measure multiple points, unmanned aerial vehicles (UAVs) must be flown in formation. perform such flights, sensor information generated by each UAV should shared via communications. Although a variety of studies have focused on the algorithms for formation flight, these mainly demonstrated performance flight using numerical simulations ground robots, which do not reflect dynamic characteristics UAVs. In this study, an onboard sharing system and UAVs...

The impact of high-voltage–high-frequency (HVHF) amplifiers on echo-signal quality is greater with very-high-frequency (VHF, ≥100 MHz) ultrasound transducers than low-frequency (LF, ≤15 transducers. Hence, the bias voltage an HVHF amplifier must be stabilized to ensure stable amplitudes. We propose a bias-voltage stabilizer circuit maintain DC voltages over wide input range, thus reducing harmonic-distortion components echo signals in VHF pulse-echo measurement systems. To confirm...

The after-pulsing effect is a common problem in high-speed and low-noise single-photon detection based on avalanche diodes (SPADs). This article presents dual anode InGaAs/InP SPAD (DA-SPAD) with two separate output ports that can be utilized for discriminating relatively weak signals, providing simple robust configuration of the SPAD-based system. Weak signals amplitudes below amplitude parasitic capacitive response were easily detected by DA-SPAD subtraction circuit. gated Geiger-mode...

Abstract Accurate location information is crucial for ensuring the reliability of service robots, such as field vehicles and agricultural robots. These practical robots often encounter fluctuating or inclined terrains in dynamic conditions during operation. Additionally, performance mobile depends on physical size weight localization system–physically heavy systems may degrade performance.

In this paper, multistage auction-based intelligence, surveillance, and reconnaissance (ISR) sensor coordination mechanisms are investigated in the context of dynamic uncertain mission environments such as those faced by expeditionary strike groups. Each attribute task is modeled using a hidden Markov model (HMM) with controllable emission matrices, corresponding to each ISR asset package (subset sensors). For HMM-asset pair, we evaluate matrix information gains (uncertainty reduction...

Task-asset assignment is a fundamental problem paradigm in wide variety of applications. A typical scenario involves single decision maker (DM) who has complete knowledge the weight (or reward/benefit/accuracy) matrix and can control any assets to execute tasks. Motivate by planning problems arising distributed organizations, this paper introduces novel variation problem, wherein there are multiple DMs each DM know only part and/or controls subset assets. We extend auction algorithm such...
